Improper sanitization is the number one mistake that most home brewers do. This is when so many sanitizers are now commercially available. Today we are going to talk about the wonders of peracetic-acid
On their own both are mild food-grade disinfectant. Vinegar is liberally spread over salads, paneer making, Chinese food so is definitely food grade. Hydrogen peroxide (H2O2) is famous for cleaning wounds. It breaks down into free oxygen molecules and water (harmless). Making it a perfect low-cost sanitizer for home-brewers on a budget. Just fill two spray bottles one with peroxide and second with the vinegar. Spray each equipment one after another for the best results. (doesn’t matter which order it is). And the best part is that you don’t need to wash off the surface after spraying (just allow it to evaporate and use the equipment) making it the perfect no-rinse sanitizer.
However please note that together they form a highly corrosive peracetic acid. Vinegar and Hydrogen Peroxide actually make a very potent sanitizer, so potent that it may result in permanent scarring of the skin! Studies have shown that peracetic acid irritates the skin, eyes, nose, throat, and lungs. Greater exposure can cause pulmonary oedema and affect the kidney and liver. So please excise necessary caution when handling these potent chemicals.
